DNA Barcoding Challenges and Goals

DNA barcoding began in 2003 with Paul Hebert's idea to use short DNA sequences to identify species, similar to scanning barcodes at a supermarket. Initial workshops addressed the feasibility of this concept. Today, over a million barcode records exist, with goals to expand to five million records and 500,000 species, supported by international collaboration.
